Microsoft announced the hire of former ten-year Yahoo exec Dr. Qi Lu today as President of their Online Services Group. He’ll report directly to CEO Steve Ballmer.

Here’s the email Ballmer sent to all Microsoft staff forty minutes ago:

    From: Steve Ballmer
    Sent: Thursday, December 04, 2008 1:39 PM
    To: Microsoft – All Employees (QBDG)
    Subject: New Leader of Online Services Group

    Search, advertising and online services are critical to Microsoft’s long-term strategy. To succeed, we need the right talent. Today, I’m pleased to announce that Qi Lu will join Microsoft as president of our Online Services Group. Qi will oversee all efforts in search, our online advertising platform, and all of our online information and communications services. Qi will join Microsoft on Jan. 5 and report to me.

    Qi is one of the most respected technical minds in the industry. He comes to Microsoft after 10 years at Yahoo, where he most recently served as executive vice president of engineering for all of Yahoo’s search and advertising development efforts. Before joining Yahoo, Qi was a researcher at IBM’s Almaden Research Center. He has a doctorate in computer science from Carnegie Mellon, and he holds 20 U.S. patents.

    Qi’s combination of deep technical expertise, proven leadership capability and broad business knowledge is rare in our industry. There is no one better qualified to guide our work to reinvent search and online advertising.

    While I’m excited that Qi is joining Microsoft, I’m sorry to share the news that Brian McAndrews has decided to transition out of the company. Brian came to us with the acquisition of aQuantive in 2007. Since then, he has helped build a world-class business in online advertising that provides a solid foundation for future growth. I have great respect for the important contributions Brian has made to Microsoft, and I wish him the very best in the future.

    On Monday at 4 p.m. Pacific Time, Qi will join me at Café RedWest for an Employee Town Hall. I encourage you to attend or to watch the webcast. If you have questions for Qi or me, please send them in advance to and we’ll try to answer as many as possible.

Jerry Yang just put up a blog post on his reasons for stepping down as CEO of Yahoo.

In it, he highlights the successes of the past 18 months. Yahoo is now “rewired,” the new ad platform has been launched “that we think will transform how ads are bought and sold online,” and Yahoo remains “first or second in more than 20 product categories.” And he ends with the promise “that I will always bleed purple.” No matter what his critics might say.

The post is reproduced below in its entirety:

As you’ve no doubt already read, I’ve decided that I will step down from my role as Chief Executive Officer after my successor has been selected.

Ever since founding Yahoo! with David Filo 13 years ago, I’ve been passionate about this company, its brand, its employees, and the millions of people around the world who consider it their online home. That’s why I accepted the Board’s request to become CEO in June 2007, taking on the challenge of transforming Yahoo! at a time when the industry was evolving quickly and we needed to rethink and restructure our business.

And despite the tough external environment that we face, I truly believe we’ve made tangible progress in bringing our strategic vision to life. Most significantly, we’ve rewired our entire network to create a Yahoo! that has opened its doors to outside publishers and developers. We’ve launched an advertising platform that we think will transform how ads are bought and sold online. And we’ve continued to grow our audience –- standing first or second in more than 20 product categories and demonstrating that Yahoo! is the place users turn for major events like the Olympics and the Elections.

And now I believe the time is right for us to bring in a new leader –- someone who will build on the important pillars we’ve put in place and who will take the reins on the critical decisions our company faces. As for me, I’ll be returning to my role as Chief Yahoo and board member once my successor is named. I’ll go back to focusing on our global strategy, product excellence, technology innovation, and working with the Board and our executive team to help Yahoo! realize its full potential.

It’s been an extraordinary year here at Yahoo! –- for all of us. I’m really proud of the determination and resilience of Yahoos around the world who are so committed to giving you the best Internet experience possible. It is for them, and for you, that I will always bleed purple.

Jerry Yang
Chief Yahoo! and CEO
